Weather in September
Temperature
The average high-temperature in September, at a still hot 88.9°F (31.6°C), reveals a modest deviation from August's 90.7°F (32.6°C). Miles City observes an average low-temperature of 75°F (23.9°C) during September.Heat index
September's average heat index is estimated at an extremely hot 109.4°F (43°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
